Hard adhesive bodies and exporting soft adhesive two pieces are typically included in Overmolding products. One form of Overmolding is the Elastomer + Hard Plastic molding technique. The result typically consists of a main body portion (hard plastic) and an outsourced part (soft plastic). The hard plastic body is created during the production phase and then placed in the outsourcing mold to generate the soft plastic injection.
The Overmolding die can be used if the product output is poor. First, create a series of hard molds, and then manually press the hard plastic into the mold to create soft plastic. With a modest amount to prevent vacancy, the back of the soft mold is consistent with the main body of the hard mold. To remove glue without leaving an empty spot, the glue component should employ the strong plastic main body.
Products for Multi Shot that combine Elastomer + Hard Plastic are becoming more and more prevalent in our lives. Its products offer more robust functional purposes, superior impact resistance and buffering performance, soft touch textures, as well as other exceptional qualities.
The following materials are utilized in Elastomer + Hard Plastic:
Hard plastic materials: ABS, AS (SAN), GPPS, HIPS (475), PA (PA6, PA66) and its modified materials, PC and its modified materials, PE, POM, PP, and etc.
Soft plastic materials: TPE, TPR, TPU, TPV, TPEE, PVC, etc.
Elastomer + Hard Plastic Molding, it can also call double injection molding
The products of Elastomer + Hard Plastic Molding are made up of two procedures: first the hard plastic will be formed in the first set of molds, and the soft plastic will be injected into the second set of molds to create an Elastomer + Hard Plastic product. If the circumstances allow, it is also possible to use a Dual Shot Machine for injection molding.
This soft electronic shell was created by CN Mould & Plastic Limited using an Elastomer + Hard Plastic Molding method. TPE material was used to cover hard PC material, giving the pieces a soft touch and improved sealing.
The hard plastic body is created during the production phase and then placed in the outsourcing mold to generate the soft plastic injection.
The temperature resistance of the elastomer overmolded onto hard plastic will depend on the specific elastomer used. Silicone-based elastomers, for example, can withstand high temperatures, making them suitable for high-temperature applications. However, it is important to consult with material suppliers and experts to select the appropriate elastomer and plastic combination based on the desired operating temperature range.
Yes, elastomer overmolding onto hard plastic can enhance chemical resistance depending on the elastomer used. Some elastomers offer excellent chemical resistance and can provide a protective barrier against specific chemicals, preventing damage to the hard plastic substrate.
